Structural evolution at the oxidative and reductive limits in the first electrochemical cycle of Li1.2Ni0.13Mn0.54Co0.13O2

Abstract

Practical application of high-energy-density lithium-rich materials remains a challenge due to issues including voltage fade and poor energy efficiency. Here the authors report a novel densified phase together with a trick to recover capacity in these materials that could help in curing their practical limitations.
